Police are turning to other leads after a search for a missing man at an Abington pond on Saturday turned up no results although the man’s car was found nearby.

Police searched the pond for Stephen Hender, a 60-year-old brittle diabetic who has been missing since Wednesday, said Abington Police Chief David Majenski.

Hender’s gray 2009 Nissan Maxima was found at Island Grove Park in Abington Friday evening, resulting in a canine search of the 11-acre park. The car was found just over 2 miles from Hender’s Abington home.

“It was not unusual for Mr. Hender to go to that particular pond,” Majenski said. “Many times he and his wife would go down to the pond with cups of coffee and enjoy the scenery there. So that would be not be an unusual spot for him.”

Six canine units and a bloodhound failed to find evidence of Hender’s whereabouts on Friday, so police began the pond search about 7:30 a.m. Saturday.

A robotic camera scanned the 35-acre Island Grove Pond where a command station with medics was set up nearby.

The Quincy police dive team also searched the surface of the pond from a small boat and searched the water with a sonar device. Quincy police divers were also on scene in case they were needed to enter the water. The search was executed with officers from the Metropolitan Law Enforcement Council, a group of local law enforcement officers who share resources as necessary.

“We’re fairly confident, as confident as you can be given the circumstances, that he was not in the pond,” Majenski said. “It’s not an exact science.”

The police chief said the investigation is still under way as officers have other avenues to pursue.

A Type 1 diabetic, Hender wears an insulin pump on his hip, his wife, Cecelia Hender, said, and changed it every three days. He would have needed to change the pump either Wednesday night or Thursday morning, she said, but it is possible the pump malfunctioned.

If his blood sugar spiked or dropped too low, Cecelia Hender said it is possible her husband passed out, leaving him at risk of falling into a diabetic coma. Brittle diabetics are more prone to unexpected swings in glucose.

Abington Deputy Police Chief Chris Cutter said police don’t suspect foul play and they have nothing to indicate this is anything more than a medical issue.

“We’re still asking for the public’s help if they see or hear anything, to be vigilant,” Majenski said. “The case is still open and active.”
